The OP was after transforming a single XML file with different
stylesheets based on the type of client device used, including mobiles.
The only way to this is to detect the user-agent server side and use the
correct stylesheet.

The idea that you can list xml-stylesheet processing instructions in the
XML each with a media type and then have the device correctly pick that
stylesheet is fantasy - what constitutes a 'handheld' anyway?  It may
have been devised with good intentions, but in practice you need one
stylesheet per device as the ability of each device varies massively.
In practice most XML content destined for mobile devices get transformed
into a proprpetary format and then goes through proprietary software
which converts it to code suitable for the phone making the request.
